How can I extract the tempo from a track which was recorded freely, not to a metronome and have Logic X build a tempo map? It is pretty rhythmic with no rallentandos or big deviations. Or if I could tap it in or visually put in the beats, I could do that too. But i just don't know how to do this in X. I want to add a 'drummer' track. Right now, I can get the drummer track to start in the right place but the tempo is wrong, even though I used Detect Tempo of Selecte Region and set it to that.
